space between two tool buttons and hboxlayout

[andreahmed]

I'm trying to remove two tool buttons and add the other widgets and add an hboxlayout using an even filter if the window is shown or hidden. The problem is when I remove the spacer the horizontal one, the two buttons are tied together successfully, but when I add a widget, there is a space between the tool button and the widget as shown in the figure. how would I remove that space ?

here is the initialization

setWindowTitle(tr("Points of Interest"));
    m_splitter->setContentsMargins(0, 0, 0, 3);
    m_gridLayout = new QGridLayout(this);
 
    m_gridLayout->addWidget(m_splitter, 0, 0, 1, 1);
    m_hBoxLayout = new QHBoxLayout(this);
    m_gridLayout->addLayout(m_hBoxLayout, 1, 0, 1, 1);
    m_hBoxLayout->addWidget(m_myPoiButton);
    m_hBoxLayout->addStretch();
    m_hBoxLayout->addWidget(m_myPoiFilterButton);
    m_gridLayout->setVerticalSpacing(0);

setWindowTitle(tr("Points of Interest"));
    m_splitter->setContentsMargins(0, 0, 0, 3);
    m_gridLayout = new QGridLayout(this);

    m_gridLayout->addWidget(m_splitter, 0, 0, 1, 1);
    m_hBoxLayout = new QHBoxLayout(this);
    m_gridLayout->addLayout(m_hBoxLayout, 1, 0, 1, 1);
    m_hBoxLayout->addWidget(m_myPoiButton);
    m_hBoxLayout->addStretch();
    m_hBoxLayout->addWidget(m_myPoiFilterButton);
    m_gridLayout->setVerticalSpacing(0);

Hard to tell without any screenshot or the ability to execute this, but have you checked if the space is caused by layout spacing?
